Step 2. test with led matrix.

This is where we encountered the majority of our issues. Due to the limitation of library resources in Particle, we had to write the algorithms, animations from scratch frame by frame. Particle does not support 64 bit reading, and we therefore needed to code in binary terms.

Step 3. finishing up the connectivity between the 2 devices.

Writing up codes and publishing on particle to have 2 screens sharing the same screen and sharing data from each other. 

Step 4. polishing the aesthetics of the watch.

Aesthetics matter, even for a project prototype of a course. We decided to go all "retro" with every part readily available in the studio, even including the band. For the demo, we used portable chargers, which enabled us to hide all rest of the parts in sleeves or pockets, avoiding unnecessary distractions from the audience. After all, audience care about your actual ideas, not every detail of how they work.
